    key words: Plasticizer Status Outlook
    Food contact materials are also known as food packaging materials, commonly abbreviated as Food Contact Materials. As a "close clothing" for food, FCMs are also known as "special food additives"
    food
    . In the process of contact with food, food contact materials and products of toxic and harmful substances will migrate and infiltrate into food, resulting in food contamination.
    1 Plasticizer in Liquor
    In the modern liquor industry, most of the production process has eliminated the use of traditional blood containers and replaced them with durable materials such as plastic or stainless steel containers. Especially in the production process used in the pipeline, plastic products with its excellent plasticity and stretchability can be widely used. Plastic products are commonly used in everything from small gaskets in wine pumps that provide conveying power to filling heads that come into contact with bottles when filling liquor.
    plasticizers, also known as plasticizers, are phthalates, benzoates, fatty acids, alkaloids and chlorinated paraffins, among which phthalates (Phthalic Acid Esters, abbreviated PAEs, also known as pyresters) account for the largest proportion, accounting for about 70% of the total plasticizer
    production

    2 Research Status
    2.1 Sources of Phthalates
    Plasticizers are found in plastics, cosmetics, clothing, toys and food that are exposed to everyday life. Xu Xizhu et al. believe that phthalates mainly include natural sources and synthetic sources. It is believed that artificial synthesis is mainly produced by phthalates in the form of terpenes or xylene chlorine, and then by chemical reaction in combination with the corresponding alcohols, and the natural source is mainly the synthesis of microorganisms. Wang Hong et al. analyzed the source of plasticizers in liquor, and concluded that phthalates plasticizers had a higher rate of migration in ethanol, which was inevitable in the process of liquor production and processing and storage, and put forward corresponding measures to reduce the production of plasticizers.
    He Tao et al. discussed the pollution of plasticizers in drinking water sources, and by studying the water quality during the dry period of a backup water source in the south, it was found that the concentration of phthalates in the area was high relative to similar areas at home and abroad, which required risk assessment and management of the environment of the water source to reduce the risk of phthalates. Wang Hongfen et al. analyzed the pollution status of phthalates in the environment, listed the pollution situation in the environment and its harm to human and animals, and put forward preventive measures.
    not need to be added to the traditional liquor brewing process. With the development of liquor industry, plastic products are gradually applied to liquor production lines and packaging storage process, liquor delivery process involved in the pipeline, wine pump head involved in the entry and exit of latex tubes or gaskets, liquor storage process used in the plastic wine barrel, wine process used to seal the cylinder use of plastic cloth, finished wine packaging use of plastic lid, finished packaging plastic bags or plastic bottles (barrels), etc. , are plastic agent into the liquor.
    2.2 Toxicity Study of Phthalates
    Studies by Yu Qiumei et al. have concluded that phthalates are a class of environmental estrogen substances, and the International Cancer Institute (IARC) has classified DEHP as a potential cancer promoter, considering it to be reproductively toxic and developmentally toxic

    . Zhang Jing et al.'s research believes that phthalates plasticizers are widely present in people's daily life contact with all kinds of toys, children's products, food contact materials and textiles, such as ingestion channels, exposure, so there is a higher health risk.
    Zhang Na studied four phthalates (DBP, DEP, DOP and DEHP), and evaluated the germination rate and root elongation inhibition rate of root plants at individual and physiological levels, and concluded that DBP was more vulnerable to crop victims than DEP, DOP and DEHP, and had obvious reproductive and developmental toxicity. Yang studied phthalates on neural stem cells and bone marrow stem cells in mice in Kunming, and concluded that DBP, DEHP and DEEP can produce significant damage to bone marrow stem cells, affect cell proliferation, and have a strong toxic effect on neural stem cells and bone marrow stem cells. Cao Guozhou et al. carried out a risk assessment of the use of phthalates in food contact materials, concluded that the dose of human exposure to plasticizers has posed a health risk, and suggested limiting the use of phthalates in food contact materials.
    2.3 Study on the detection method of phthalates
    Cao Guoqing gave an overview of the hazards and detection methods of plasticizers in liquor, introduced the sources and hazards of plasticizers in liquor, put forward qualitative and quantitative basis for mass spectrometry fragments of
    plasticizers, and listed the conditions for chromatographic separation and mass spectrometry map
    Wang Minglin et al. used the base solid phase dispersion-gas chromatography mass spectrometry method to determine 5 phthalates in vegetables, and proposed that the pre-treatment method of vegetable samples by Floridium silicone soil and graphite carbon black grinding uniform, with ethyl acetate wash purification. Wang Chaoying et al. used solid phase micro-extraction method to treat atmospheric samples, and used high-efficiency liquid chromatography to determine trace phthalates in the environment, and put forward the conditions for the optimization of solid-phase micro-extraction. Lu Chunshan et al. studied the ultrasonic extraction-solid-phase extraction purification/GC-MS analysis method, and examined the extraction and purification methods of different kinds of food, and the results showed that the base removal rate of the purified food extract reached 80%. Wang Suming proposed to establish different pre-treatment methods according to the characteristics of food substations, and used ultrasonic extraction and liquid extraction methods to treat samples for vegetable sauces, and concluded that the samples could achieve better results after double purification test results. Tao Ran selected 10 components of phthalates using ultraviolet spectrophospation method, high-efficiency liquid chromatography, gas chromatography and other analytical instruments to establish at the same time to determine the residue of 10 phthalates in food analysis methods. Pang Shimin et al. used ultrasonic extraction-gas chromatography to determine phthalates plasticizers in food packaging preservation bag materials, optimized the pre-sample treatment method, and concluded that the ultrasonic extraction effect of toluene solvent was better. Yu Xiongfei et al. studied the application of Fourier transform infrared spectroscopy to achieve rapid identification of PVC and phthalates plasticizers. Wang Wei and others set up a thin layer scanning method to determine phthalates (DMP, DEP, DBP and DEHP), respectively, with cyclic hexane soaked plastic infusion equipment, ultrasonic extraction treatment, good separation effect, can simultaneously determine the plastic infusion equipment and bag glucose liquid phthalates 32 (2 ethyl) - hexyl esters.
    3 Research Outlook on Plasticizers in Food
    After the exposure of plasticizer incidents in liquor in 2012, the
    Fedic safety
    regulatory authorities asked liquor companies to thoroughly investigate the production process. In 2013, the State Food and Drug Administration issued a Notice on Further Strengthening the Supervision and Administration of Liquor Quality and Safety, requiring
    regulatory departments at all levels to
    further strengthen the supervision and management of liquor quality and safety, incorporate plasticizer projects into the contents of food licensing and audit, and urge enterprises to ensure the quality and safety of liquor. Studies have shown that plastic containers and plastic pipes are the root cause of plasticizers in liquor, therefore, liquor production enterprises strictly prohibit the use of plastic products for the filling, transport of liquor, all workshop wine pipeline replacement for stainless steel materials, strictly prevent plastic products direct contact with the wine body led to phthalates migration occurred. Liquor production enterprises will phase out plastic-related pipelines and containers, and gradually use stainless steel pipelines and containers for organized production, by reducing the direct contact with plastic products, to avoid causing alcohol pollution. Phthalates will gradually withdraw from the field of food contact materials production with the development of the chemical industry.
    at the same time, in order to develop rapid detection technology of plasticizer content, Dou Waizhi et al. successfully realized the rapid detection of DEHP and DINP in liquor
    .
    by studying the detection equipment built using FAIMS (strong field asymmetric waveform ion migration spectrum) chips. Convenient and fast detection technology, can effectively ensure the supervision of product quality, easy for liquor production enterprises in the production process at any time to monitor the content of phthalates in the wine body, to help production enterprises take effective measures to prevent the plasticizer migration or pollution of the wine body. Compared with the national standard method testing of plasticizers, rapid testing technology is low cost and high efficiency, which can greatly reduce the inspection and testing workload during the screening process.
    Because PAEs are not only found in plastic products, but also contain PAEs in air and water, Zhao Jing et al. used aeration biodegradation of the plasticizer DHP and DEHP respectively, with removal rates of 95.5% and 90.3%, respectively, and speculated on possible degradation pathways for PAEs. Therefore, the future liquor enterprises for how to remove the PAEs ingredients in the body will become an important topic of research.
